Fuel Pressure 5.0
I have a 1987 mustang gt 5.0 & I replaced the fuel pump, pressure regulator, O- rings on injectors & still have low fuel pressure of 34lbs. What should the pressure be & what can I do to fix this.

I think 34 is probly at the min you want but quite acceptable on a stock moter.
Assuming you not experiencing any drivability issues and its starting and idling good I wouldn't dwell to much on that number.
Any where between 35-41 psi is fine but different gauges may give a +or- 1 psi so no biggy.
